New here? These answers walk you through B2BB2G step by step, grouped by topic.
B2BB2G is an online marketplace where companies and public organizations post products and requests and connect with each other.
You can post products for sale on a board, or post a request to find what you need.
Every member is shown by a numeric UID (a unique member number) instead of a real name.
You join with an invite link (a sign-up web address that another member sends you). Depending on site settings, only invited people can join.
Three required items and one optional item.
The 'Agree to all' option at the top checks everything at once.
A UID is a numeric number given to each member. It is the main way members are identified on the site.
Other members see this UID instead of your real name.
If your browser's language is Korean, the site shows Korean automatically from the first visit — no change needed.
To change it yourself, press the globe icon and pick a language. [PC] the globe on the right of the header. [Phone] press the menu button (≡) at the top right, then Language inside the drawer.
The globe is also on the login and sign-up screens (top right), so you can read the sign-up guidance (such as the password rules) in Korean too.
Once you pick a language, that choice is kept.
The left logo (B2BB2G) is the same on PC and phone. Pressing it returns you to the first page.
[Wide screen (PC)] The board menus spread across the middle: Commercial, Industrial, EPF+C(Local), RFQ & ITB, Events, Services, Notices, FAQ. On the right are a magnifying glass (search), a globe (language), and a bell (notifications); after you log in, a round profile photo (= 'My Menu') appears.
[Narrow screen (phone)] The top bar shows only the logo, the bell (notifications), and a three-line menu button (≡). The board menus, search, language, My Menu and login all live inside the drawer that opens when you press the menu button (≡).
In short: what is spread across the top on PC is gathered into the one menu button (≡) on a phone.
[PC] After logging in, press the round profile photo at the top right of the header — 'My Menu' opens.
[Phone] Press the menu button (≡) at the top right to open the drawer; the same 'My Menu' items are near the top of it, next to your profile photo.
Inside are Dashboard, Activity (My posts, Inquiries, Saved products), Create (Add a product, Post a sourcing request), Community (Feed), and Account (Profile, Security).
The dashboard is the screen where you manage your activity in one place.
Inside the dashboard a vertical menu list sits on the left (on a phone it appears as a row of swipeable tabs at the top): Dashboard, My posts, Add a product, Apply for a badge, My referral link, Inquiries, Notifications, Profile, Security, Mini homepage, Coordinator.
[PC] Press the magnifying glass icon on the right of the header.
[Phone] Press the menu button (≡) at the top right, then press Search inside the drawer.
Type the word you want to find and results appear right away.
You see them at the bell icon on the right of the header. When there is a new notification, a dot appears on the bell.
You can also see them at 'Notifications' in the dashboard's left menu.
Commercial is for ready-to-use consumer goods.
Industrial is for equipment, parts, and manufacturing.
EPF+C(Local) is for energy and infrastructure projects.
RFQ & ITB is the board for posting requests (quotes and bids).
Post ready-to-use consumer goods on Commercial.
Post equipment, parts, and manufacturing items on Industrial.
Post energy and infrastructure projects on EPF+C(Local).
On the product form, upload product photos in the photo box. You can upload several.
In the specs box, write detailed product information such as size, material, and quantity.
The more detailed your photos and specs, the better others understand the product.
Yes. On the product form, press 'Save draft' to save it as a draft (a post you are still writing and have not posted yet).
Open it again later, finish it, and press 'Register'.
When you press 'Register', the post does not go public right away; it first enters a 'Pending review' state.
After the operations team checks it and approves, the post becomes public.
A product is a post that shows an item you are selling.
A request is a post that announces what you need and looks for someone to provide it. Use it to receive quotes or bids.
Requests are handled on the RFQ & ITB board.
No. You can set a deadline, or leave it open with no deadline.
If you set a deadline, you receive replies only until then.
You see them on the 'RFQ & ITB' board in the middle of the header.
This is where requests looking for quotes or bids are gathered.
Yes. When posted, a request also goes public after the operations team checks it.
Once public, others can send an inquiry from the request's detail page.
No. The operations team checks your inquiry first.
After checking, they forward it to the other person, or if it cannot be forwarded, they return it to you with a reason.
Here you see both received and sent inquiries.
Yes. The inquiry list has a read receipt.
When the other person reads it, you can confirm it by the read mark.
When the operations team checks an inquiry and finds it cannot be forwarded, they return it with a reason.
You can read the reason, fix the message, and send it again.
You create invite links on the 'My referral link' screen. There are two ways in.
No. An invite is single-use and only one person can join with it.
Once it is used to join, it cannot be reused or shared. It also expires automatically.
Yes. As long as it has not been used, you can re-copy an invite link anytime from the 'My referral link' list.
When you create the invite, write a name or company in 'Recipient note'.
That note then shows as the title of each row in the list, so you can tell at a glance which link belongs to whom.
You can edit the note later by pressing the pencil icon on the row.
Yes. On a phone, press the 'Share' button on the invite row to open the share sheet (KakaoTalk, Messages, and so on) right away.
On a PC or a browser without share support, press 'Copy' to copy the link and paste it to send.
You can also press 'QR code' next to it to share it as a QR.
Check the status shown on each invite row in the 'My referral link' list.
Yes. You can cancel an invite that has not been used yet.
Cancel that invite in the 'My referral link' box.
A coordinator is a member granted coordinator authority directly by the operations team. They manage and help the members they invited get started.
If the member who invited you holds coordinator authority, that member is your coordinator.
Yes. You can send your coordinator a direct message (a one-to-one private message).
Open the coordinator messages (direct message) screen from the dashboard menu and ask anything you are curious about.
Only members with coordinator authority can see the list of members they invited.
※ Regular members without coordinator authority cannot see this list. Instead, they can check each invite's status (Joined, and the new member's UID) in 'My referral link'.
Coordinator authority is granted directly by the operations team. Inviting other members does not automatically make you a coordinator.
A member granted the role can view and manage the members they invited in the 'Coordinator' menu, and can receive those members' direct messages.
Yes. Even without coordinator authority, every member can create invite links in 'My referral link' to refer (invite) others.
You can check each invite's status and the new member's UID in the 'My referral link' list.
However, the 'Coordinator' screen that gathers and manages all your referred members in one list is available only to members granted coordinator authority by the operations team.
Other members see your UID (unique member number) as the main identifier, not your real name.
Your bio and company name show what you set on the edit screen.
A badge is a mark that shows a member's trustworthiness. For example, there is a Verified badge.
With a badge, others can connect with more confidence.
No. After you apply, it goes through an operations-team review.
When the review is finished and approved, the badge is granted.
Two-step verification protects your account by checking once more beyond your password.
App lock is a feature that locks the site once more when you open it.
You unlock it with a six-digit PIN (a numeric passcode) or with fingerprint or Face ID.
Turn it on in the 'My Menu > Account > Security' screen.
Yes. Go to 'My Menu > Account > Security': the list of logged-in devices is near the top, with your login history below it.
To sign out only certain devices: tick the checkbox next to each device you want, then press 'Sign out selected devices'. Your current device has no checkbox, so you cannot accidentally sign yourself out.
There are also two buttons at the top right: 'Sign out other devices' keeps this device and signs out the rest, while 'Sign out everywhere' signs out every device including this one.
If you see a device you do not know, sign it out and change your password too.
Even if you did not agree at sign-up, you can enable it here — and turn it off again anytime.
Verified members can run a simple introduction page at 'Dashboard left menu > Mini homepage'.
See verified membership information on the membership page.
For questions, message your coordinator (the person who invited you) with a direct message, or check 'FAQ' and 'Notices' in the middle of the header.
